The 9000 Series is a modular based Gigabit Ethernet Switch with up to 4 slots for ports and one slot for the CPU module. Please

follow the steps below for adding, removing, or swapping modules in the 9000 series switch. Technicians performing the

following steps should wear proper anti-static equipment to protect the circuit boards. WARNING: The 9000 series switch is

NOT hot swappable. Removing or adding modules while the power is still on can damage the equipment.

Adding or Replacing a Module:

1. Remove power from the switch.

2. Unscrew the two thumb screws for the filler panel or module that you are replacing.

3. Using both hands pull on both thumb screws to slide the filler panel or module you are replacing off the 9000BP.

4. Align the new module such that it slides on the rails and firmly push it into the unit.

5. Screw both thumb screws down till they are finger tight.

6. Reapply the power and configure the slots on the 9000 either through the web management interface or the serial

management interface.

NOTE: Modules should be installed in slot order (from left to right). So in a 2 slot configuration Slots A and B are populated.

Empty slots must be covered with a 9000-FP to meet emission standards.

Replacing a CPU Module:

1. Remove power from the switch.

2. Unscrew the two thumb screws for the CPU module that you are replacing.

3. Using both hands pull on both thumb screws to slide the CPU module out of the 9000BP.

4. Align the new CPU Module such that it slides on the rails and firmly push it into the unit.

5. Screw both thumb screws down till they are finger tight.

6. Reapply the power to the switch.

NOTE: All configuration settings are saved to the NVRAM which is stored locally on the CPU Module. If you replace the CPU

Module all settings will move with the CPU Module. You can save and download a custom configuration to a TFTP or an

FTP server. The switch’s MAC Address and IP Address will also move with the CPU Module.

DIN-Rail Mounting

Install the unit on a standard 35mm Din-Rail. Recess the unit to allow at least 5” of horizontal clearance for fiber cable bend

radius.

To mount the unit to the 35mm din-rail, place top edge of the

bracket on the back of the unit against the din-rail at a 45° upward

angle. Lower the bottom of the unit until it snaps into place.

To remove the unit from the 35mm din-rail, place a

flat head screwdriver into the release clip at the bottom of

the unit, and push down on the clip until it disengages

from the bottom of the unit from the din-rail. Lift the

bottom of the unit up at an approximate 45° upward angle

to completely remove the unit.

Most N-Tron™ products are designed to

be mounted on industry standard 35mm DIN-

Rail. However, DIN-Rail mounting may not

be suitable for all applications. Our Rack

Mount Assembly (P/N: 900-RM) may be

used to mount the 9000 Series to standard

19" racks as an option.

5/17/2007 page 12 of 138

Panel Mount Mounting

Install the unit directly on a wall or sturdy panel such as a bulkhead. Recess the unit to allow at least 5” of horizontal clearance

for fiber cable bend radius.

To bulkhead mount the unit, place top edge of the bracket on the back of the unit against two screws at a 45° upward angle.

Lower the bottom of the unit until it is flush with the wall, and secure the bottom of the unit with two more screws.

To remove the unit from a wall, remove the bottom two screws that secure it to the wall and slide the unit up until the top two

screws will fit through the larger holes on the unit. The switch should then freely come away from the wall.

N-TRON SWITCH GROUNDING TECHNIQUES

The grounding philosophy of any control system is an integral part of the design. N-Tron switches are

designed to be grounded, but the user has been given the flexibility to float the switch when required. The

best noise immunity and emissions (i.e. CE) are obtained when the N-Tron switch chassis is connected to

earth ground via a drain wire. Some N-Tron switches have metal din-rail brackets that can ground the

switch if the din-rail is grounded. In some cases, N-Tron switches with metal brackets can be supplied with

optional plastic brackets if isolation is required.

Both V- legs of the power input connector are connected

to chassis internally on the PCB. Connecting a drain wire

to earth ground from one of the V- terminal plugs as

shown here will ground the switch and the chassis. The

power leads from the power source should be limited to 3

meters or less in length.

As an alternate, users can run a drain wire & lug from any of the Din-

Rail screws or empty PEM nuts on the enclosure. When using an

unused PEM nut to connect a ground lug via a machine screw, care

should be taken to limit the penetration of the outer skin by less than 1/4

in. Failure to do so may cause irreversible damage to the internal

components of the switch.

Note: Before applying power to the grounded switch, you must use a

volt meter to verify there is no voltage difference between the power

supply’s negative output terminal and the switch chassis grounding

point.

The use of shielded cables between devices is not required for most N-Tron devices (please consult the user

manuals for specific details). If the use of shielded cables is required, it is generally recommended to only

connect the shield at one end to prevent ground loops and interfere with low level signals (i.e.

thermocouples, RTD, etc.). Cat5e cables manufactured to EIA-568A or 568B specifications are required for

use with N-Tron Switches.

In the event all Cat5e patch cable distances are small (i.e. All Ethernet devices are located the same local

cabinet and/or referenced to the same earth ground), it is permissible to use fully shielded cables terminated

to chassis ground at both ends in systems void of low level analog signals.

CONNECTING THE UNIT

For FX/FXE units, remove the dust cap from the fiber optic connectors and connect the fiber optic

cables. The TX port on the FX/FXE models should be connected to the RX port of the far end station. The

RX port on the FX/FXE versions should be connected to the TX port of the far end station.

For 10/100 Base-TX ports, plug a Category 5E twisted pair cable into the RJ45 connector. Connect

the other end to the far end station. Verify that the LNK LED’s are ON once the connection has been

completed. To connect any other port to another Switch or Repeater, use a standard Category 5 straight

through or crossover cable.

N-Tron recommends the use of

pre-manufactured Cat5E cables to ensure

the best performance. If this is not an

option and users must terminate their own

ends on the Cat5E cables; one of the two

color coded standards shown to the right

should be utilized. If a user does not

follow one of these two color code

standards then the performance and

maximum cable distance will be reduced

significantly, and may prevent the switch

from establishing a link.

SERIAL INTERFACE

The 9000 series switches provide an EIA-232 interface accessed via a 9 pin female connector (labeled

‘COM’ on the unit). This is used to access the Command Line Interpreter (CLI). The pin-outs are shown

below:

Overview of Advanced Features

Mode of Operation

Each port on the switch can be configured into different modes of operation as shown below:

Copper Ports: 100Base Fiber Ports: 1000Base Fiber Ports:

- Half Duplex - Full Duplex - Full Duplex

- Full Duplex

- Auto Negotiation

Half Duplex

In half duplex mode, the CSMA/CD media access method is the means by which two or more

stations share a common transmission medium. To transmit, a station waits (defers) for a quiet period on

the medium (that is, no other station is transmitting) and then sends the intended message in bit-serial

form. If, after initiating a transmission, the message collides with that of another station, then each

transmitting station intentionally transmits for an additional predefined period to ensure propagation of

the collision throughout the system. The station remains silent for a random amount of time (backoff)

before attempting to transmit again.

Full Duplex

Full duplex operation allows simultaneous communication between a pair of stations using point-to-

point media (dedicated channel). Full duplex operation does not require that transmitters defer, nor do

they monitor or react to receive activity, as there is no contention for a shared medium in this mode.

Auto Negotiation

In Auto Negotiation mode the port / hardware detects the mode of operation of the station that is

connected to this port and sets its mode to match the mode that of the station.

Port Security

Port Security provides a mechanism to detect any intruder in the network. When security is enabled

on the port, the port stops learning new MAC addresses on that port and if it receives any packet with a

source MAC address that is not in the address table, the packet will be discarded.

Port Mirroring

A Mirroring Port is a dedicated port that is configured to receive the copies of Ethernet frames that

are being transmitted out and also being received in from any other port that is being monitored.

Port Trunking

Port Trunking is the ability to group one or more network ports to increase the bandwidth between

two machines (switch or any work station). This feature allows grouping of high-speed connectivity and

provides redundant connection between switches, so that trunk can act as a single link between the switches.

Priority Tagging (QoS)

IEEE 802.1p priority tagging is supported for two classes of services along with bandwidth support

per priority level. Transparent mode is supported through configuration wherein if the field is set, the tag

bits are ignored. The User can configure up to 8 different priority levels per port. Also priority overriding

(overriding the tagged filed) can be enabled or disabled by the user.

Virtual LAN

The switch provides support for setting up both tagged Virtual LANs and port based Virtual LANs.

A port may belong to any number of Virtual LANs. The VLAN membership of a station is determined by

the VLAN(s) that have been defined for the port to which the station is connected. If a station should move

from one port to another, it loses its current VLAN membership and inherits that of the new port it is

connected to.

A Default Virtual LAN exists to which a port, which is not a member of any other Virtual LAN, will

belong. This allows the switch to operate as a ‘normal’ Bridge when it is used in a network. A port is

automatically removed from the Default VLAN when it is reconfigured to belong to another Virtual LAN.

Using Tagged VLANs the switch has the ability to take non-tagged packets in some ports, add a

VLAN tag to the packet and send it out tagged ports on the switch. The VLANs can also be configured to

accept tagged packets in tagged ports, strip the tags off the packets, and send the packets back out other

untagged ports. This allows a network administrator to set up the switch so he can support devices on the

network that do not support VLAN Tagged packets. The administrator can also set up the ports to discard

any packets that are tagged or to discard any packets that are untagged based on a hybrid VLAN of both

tagged and untagged ports, and using the VLAN Ingress Filter on the switch.

The 9000 Series switch also has the ability to allow overlapping VLANs. Overlapping VLANs

gives the user the ability to have one or more ports share two or more VLAN groups. For more information

and examples on how this could be implemented please see our website’s technical documents.

Rapid Spanning Tree Protocol

The rapid spanning tree protocol as specified in IEEE 802.1D-2004 is supported. One Spanning Tree

per a unit is supported. Besides a Spanning Tree per VLAN is also supported.

The Rapid Spanning Tree Protocol (RSTP) supersedes the Spanning Tree Protocol (STP) which was

described in IEEE 802.1D-1998. The RSTP is used to configure a simply connected active network

topology from the arbitrarily connected bridges of a bridged network. Bridges effectively connect just the

LANs to which their forwarding ports are attached. Ports that are in a blocking state do not forward frames.

The bridges in the network exchange sufficient information to automatically derive a spanning tree.

RSTP allows for much quicker learning of network topology changes than the older STP. RSTP

supports new and improved features such as rapid transition to forwarding state. RSTP also sends out new

BPDUs every hello time instead of just relaying them. RSTP interoperates with older STP switches by

falling back to the older STP when the older BPDUs are detected on bridge ports. The user can also

manually configure bridge ports to use the older STP when desired.

SNMP Traps

The 9000 Series switch supports up to 5 SNMP Trap Stations to which SNMP Traps will be sent.

The switch supports three standard traps; Link Up, Link Down, and Cold Start. SNMP Traps will be sent to

all the stations configured on the switch if a port Link goes up or down, and when the switch first powers

up.

IGMP Snooping

IGMP Snooping is enabled by default, and the switch is Plug and Play for IGMP. IGMP snooping

provides intelligent network support for multicast applications. In particular, unneeded traffic is reduced.

IGMP Snooping is configured via the console and if enabled, then operates dynamically upon each power

up. Also, there can be manual only or manual and dynamic operation. Note that “static multicast group

address” can be used whether IGMP Snooping is enabled or not.

IGMP Snooping will function dynamically without user intervention. If some of the devices in the

LAN do not understand IGMP, then manual settings are provided to accommodate them. The Internet

Group Management Protocol (IGMP) is a protocol that provides a way for a computer to report its multicast

group membership to adjacent ‘routers’. In this case N-Tron 9000 series switches provide router-like

functionality. Multicasting allows one computer to send content to multiple other computers that have

identified themselves as interested in receiving the originating computer's content. Multicasting can be used

to transmit only to an audience that has joined (and not left) a multicast group membership. IGMP version 2

is formally described in the Internet Engineering Task Force (IETF) Request for Comments (RFC) 2236.

IGMP version 1 is formally described in the Internet Engineering Task Force (IETF) Request for Comments

(RFC) 1112. The 9000 series supports v1 and v2.

N-Ring

N-Ring is enabled by default, and the switch is Plug and Play for N-Ring except that initially one

must enable an N-Ring enabled device to be the N-Ring Manager for a given N-Ring. Subsequently,

N-Ring operates dynamically upon each power up. Using N-Tron's proprietary N-Ring technology offers

expanded ring size capacity, detailed fault diagnostics, and a standard healing time of 30ms. The N-Ring

Manager periodically checks the health of the N-Ring via health check packets. If the N-Ring Manager

stops receiving the health check packets, it times out and converts the N-Ring to a backbone within 30ms.

When using all N-Ring enabled switches in the ring, a detailed ring map and fault location chart is also

provided on the N-Ring Manager’s web browser. N-Ring status is also sent from the N-Ring Manager to

the N-View OPC Server to identify the health status of the ring. Up to 250 N-Ring enabled switches can

participate in one N-Ring topology. Switches that do not have N-Ring capability may be used in an N-Ring,

however the ring map and fault location chart cannot be as detailed at these locations.
